Is this a problem (finding toxic heavy metals in glass marbles)?
The presence of these toxicants does not necessarily mean these marbles will directly harm the child using them. My concern is more for “the planet ” (i.e. our habitat) and for, well, the principle of the thing!… Regardless of regulatory standards (and the various huge, glaring loopholes within those regulations), and no matter whether there is any direct risk to the “user “ (a child), it is my firm belief that children’s toys should never test positive for any level of even one toxicant, let alone four separate potent neurotoxins and carcinogens!
Additives vs. Contaminants
Toys containing heavy metals is inexcusably offensive in principle; these levels (primarily the levels of Antimony and Arsenic found) are not simply “trace contaminants” — they are ingredients deliberately chosen and used in the manufacturing process. The colors in these particular marbles were made by adding incredibly toxic, environmentally disastrous heavy metals to the molten glass.
Primary motive: “cost-saving” vs. safer alternatives
Whereas using toxic metals to produce vibrant colors yields a cheap product that is cute, lovely, and generally thought of as harmless to the user, the direct and indirect devastating environmental contamination, and poisoning of communities — including plenty of children — throughout the world as a result of the mining, refining, and manufacturing exposure to these toxicants is profound and unavoidable. Moreover, and this is key, there are non-toxic alternatives to the use of these particular toxic substances that achieve the same results, minus the unacceptable environmental and human costs.

We have marbles from a larger box full of them, with the exact same packaging branding/graphic design, from Walmart (around 2015 I think). We play with them all the time. But I may just stick them in a jar on a shelf to look pretty…
I’m totally with you that we shouldn’t encourage/support/buy things that use these ugly manufacturing processes like this. But I wanted to make sure I understood what I read above – Having already bought these, do you think they are unlikely to cause any harm to a child’s heatlh just by handling them?
Additional question-
I bought a couple of large, greenish/blueish marbles from a display bowl on the counter at an antique shop. Should I assume that any ‘antique’, colored glass is going to have contaminates like these? Are they an issue to handle, or safe as along as we aren’t licking them?
Thank you so much for letting us ask questions like these, on your helpful posts!
Short answer is yes. Antiques in particular did not really worry about what they were adding to their products or did not recognize the dangers. There are regulations now and loop holes. But unless you can actually test the product, you won’t know for 100% certainty. I doubt the glass itself could harm you from simply playing with them though. It’s more the colouring on the inside if chipped or broken.
These were Made in China. Although it might be the same if made in the US. Maybe in Europe they would not have these contaminates? Was the glass itself laced with any toxins? Lead for instance? Or just the inside colouring to get the brilliance that we all expect?
It’s the colorants in the glass. Country of origin doesn’t really matter. I haven’t found toxicant-free marbles.
